"Because You Left" will be the premiere episode of Season 5 of Lost, and is scheduled to be broadcast on January 21, 2009.

"The Lie" will be the second episode of Season 5 of Lost, and is scheduled to be broadcast as the second hour of the Season 5 premiere on January 21, 2009.

the remaining island survivors start to feel the effects of the aftermath of moving the island, and Jack and Ben begin their quest to reunite the Oceanic 6 in order to return to the island with Locke’s body in an attempt to save their former fellow castaways.

Lindelof also suggested that the split may only be a temporary measure that will work in the show’s favour. "Let’s face it, absence makes the heart grow fonder, but there’s nothing sweeter than a reunion. All we’re willing to say at this point is that if we were to spend the entire duration of season five with the Oceanic Six trying to get back to the island, we are fully aware that the audience would strangle us."

p.s. I finally figured out what LOST is about… it’s actually LOST in Space, a very long introduction to the new Star Trek movie. Actually… Ben is actually DATA in a time warped parallel universe and the rest of the main characters are all Star Trek members in a parallel universe!
